The Josephson inductance of Indium Arsenide nanowire proximity junctions

The nonlinear Josephson inductance is an essential element in many quantum device applications including superconducting qubits. Semiconductor proximity junctions could provide additional functionality to these devices, such as gate-tunable critical currents or exotic Majorana fermions via strong spin-orbit coupling. We investigate Joesphson inductance of Indium Arsenide proximity junctions embedded in a microwave resonator based on aluminum coplanar waveguide structures. Our results on the nonlinear inductance and dissipation as a function of the current and the top-gate voltage are discussed.
